"How much does you project cost per year? How much do you cost?"
It's a serious question I asked my class the other day, and none of them could tell me. Yes, I realize that how a lab runs is not really something grad students should be overly invested in, as long as they have the resources they need. At the same time, it has an enormous impact on them directly or indirectly.
So I told them to go find out. Ask their PIs, estimate their consumables and reagent costs, etc. What surprised me most was that many of them returned to class to report that their PI had either declined to provide them information or told them they didn't need to know. Not even an estimate?
